This article is about actual problem of unsatisfactory work of system of heating of cycle air on GPA-32 Ladoga compressor unit on CS-48: there were emergency stops, caused by insufficient heating of inlet air of axial compressor.

The processes of incrustation are caused by huge amounts of dissolved salts in the heat medium. When being exploited the evaporation of the heat medium leads to the ion concentration in it and reaches its satiation. Further increase of the ion concentration leads to scaling. Heated shielding pipes are subjected to scaling more than any other elements of the heat generator.

The article analyzes the methodology and specifics of conducting local monitoring and qualitative characteristics of extracted groundwater in the system of PJSC "Gazprom" and OOO "Gazprom transgaz Ukhta" as of January 1, 2015 based. On the basis of the analysis appropriate recommendations are given.

Summarized the reasons for the violation of the dynamic stability of the drill string in the drilling process. The conditions for vibration-free running of the drill string. It is shown experimentally that oscillatory processes in the electrical drive–drill string adequately describes the two-mass model, which allows the development of the structure of electromechanical systems effectively damping oscillations of the drill string due to the capabilities of the drive.

Experiments have been carried out to evaluate the efficiency of dissolving car-bonate deposits. The effect of the reactant on the change in the filtration characteris-tics of a carbonate porous medium has been studied. The selection of components for an oil-acid compound based on the chemical product Sulfoil-K for acid fracturing in high-temperature wells was carried out. We showed the possibility of using the Sul-foil-K chemical product as a basis for preparation of acid compounds for cleaning the downhole pumping equipment from deposits of carbonate salts, as well as and additive for preparation of a filter cake removal compound based on hydrogen perox-ide. A comparative analysis of the demulsifiers Reapon OFC-D and Divoil was car-ried out.
